Thermodynamic potential of the Periodic Anderson Model with the X-boson method: Chain Approximation
R. Franco, M. S. Figueira, M. E. Foglio
The Periodic Anderson Model (PAM) in the limit has been studied in a previous work employing the cumulant expansion with the hybridization as perturbation (M. S. Figue…

X-boson cumulant approach to the periodic Anderson model
R. Franco, M. S. Figueira, M. E. Foglio
The Periodic Anderson Model (PAM) can be studied in the infinite U limit by employing the Hubbard X operators to project out the unwanted states. We have already studied this probl…
